An engineering marvel dating from 1536 to 1866, the Upper Harz Water Management System is considered one of the Harz Mountains' greatest attractions. It encompasses all the structures built to store water and transport it to mines, some of which are located far away. It is one of the largest and most significant historical water management systems in the world of mining. The Upper Harz Water Management System includes numerous reservoirs, kilometers of water channels, and underground waterways.

The "Grüner Hirsch" (Green Stag) silver mine, belonging to the Burgstätter mining district and once located about 400 meters west of the Mittlerer Pfauenteich (Middle Peacock Pond), began operations in August 1645. It was one of the few, not particularly productive, ore mines in this mining area. This mine would probably have long since been forgotten if the pond, built around the same time and named after it, had not soon played a crucial role in mining near Clausthal. The exact date of the pond's construction has not been recorded, but it likely occurred at the same time as work began at the "Grüner Hirsch," or at least before 1660. In any case, a comprehensive document from 1661, which has survived to the present day, already lists the "Grüner Hirsch Pond" as part of the water supply for the Burgstätter main drainage system.

The Huttal Ditch, along with the Huttal Watercourse and the Huttal Weir, was constructed in the 1760s. It represents a technical masterpiece and a daring experiment, as no comparable structure existed at the time. The courage and risk taken by the Upper Harz miners were richly rewarded by the flawless functioning of the Huttal Ditch and its associated structures.

There are a few ponds here due to mining - it's fun to drive over the dams

With no traffic and the fantastic scenery on both sides, this is, in my opinion, one of the most beautiful climbs in the Harz Mountains. The asphalt is mostly smooth and more than manageable. The climb is rather uneven. While the first two kilometers in particular are almost flat, the following ones settle at 7-9%. You'll have to negotiate smaller climbs up to 14% (according to Wahoo). The last kilometer to Torfhaus is unfortunately on the main road, but it's a two-lane highway.

A truly beautiful spot. It's perfect for a break. Unfortunately, there's only one bench at the top and bottom of the path.
